The [1]printk changes to finish the NBCON consoles work has been merged for Linux 6.12! This is the last remaining blocker on real-time "PREEMPT_RT" support from being upstreamed. We're now tantalizing close to seeing the real-time kernel support merged after many years of being out-of-tree patches.

Real-time kernel support could be upstreamed within the next week and a half still for the Linux 6.12 kernel. Now that the necessary printk changes are merged, it clears what was the last remaining blocker on the [2]PREEMPT_RT code from being upstreamed.

More details within [3]the printk Git merge . We are now [4]effectively at the finish line for real-time support in the kernel.

Now to see if the final merge request is submitted and no last minute issues raised by Linus Torvalds or other Linux kernel stakeholders... It would be wonderful getting the RT kernel support in Linux 6.12 given that it's expected to be this year's LTS kernel version and is also packing many other exciting features as I have been covering in numerous Phoronix articles.
